Fabricated Valve Covers

Anyone using a set of these right now?? how tall are they and what is the lift on your cam?? thx

[HP2]

I just finished a set for one of my big blocks and I'm working on some for my small block.  I'm doing it more for the look than any sort of rocker interference. My cast aluminum and stamped aluminum MP units clear just fine with roller rockers and a .509 lift.

The big block ones are 4.25 tall. My small block ones are being made at 4" tall. Unlike some you see, mine aren't all cut out around the bolt holes and instead are a big aluminum box with tubes running throught the bolt areas that will require a bolt to be dropped in from the top. I'll likely need to use some 5" bolts to put them on.

There are some on ebay like that. None I have seen have an oil cap hole though.

I'm running a really nice set from Pro-Mac Carbs.  I looked at all the offerings at the 2005 Nats and the Pro-Max ones popped out with the thick flange, steel inserts at all the hold down points and flawless TIG beads.  See my newbie intro (rumblefish72) or go to Pro-Max at http://promaxcarbs.bizland.com/Engines.chtml   Scroll to the middle engine to see the covers.  I had to grind just a little bit on the inside of one of them to take some inside TIG bead off.  It interfered with my Mopar Performance aluminum hold down blocks.  The end blocks are pretty chunky.  I trimmed the blocks by 0.050" on the Bridgeport (outside only) and everything fits nice now.  These covers don't have any hole in them.  I'm toying with the idea of putting a GZ Motorsports (http://www.gzmotorsports.com/) street vacuum pump on my car so no holes is a good thing.  BTW, several manufactures (K&N) sell bolt on breather kits.  You drill a 3/4" hole and bolt their breather mount on (no welding).

I'm running Edelbrock Performer heads, a 0.550 lift Comp mechanical cam with Crane Gold 1.5 rockers.  Edelbrock heads have a raised valve cover rail so interference isn't a problem.

The billet covers look very NHRA pro-stock .... I'd buy these covers again if I was in the market.

StrOkEr asks: how tall are the Pro-Max fabbed valve covers .... OK, time for a group shot (see picture) ...

I measured each valve cover from the gasket surface to where I hit metal like if you had a really tall rocker arm.

HEMI:                            4" sloped to 4-3/8"   <---- the winner ... the Elephant ... but we're B motors here so
Mopar Performance:         3-5/8"    <--- Second place of the B's
M/T:                              2-7/8"
Indy Cylinder Head           3-3/8"
Pro-Max:                        3-11/16  <--- Winner of B motors by 1/16"
Summit:                         3-1/4

Not that I collect B motor valve covers or anything .....

Anybody seen the Diamondback Racing Engines pieces? They look decent and are priced fairly well.

Those Pro-Max ones look like the SB ones I just got from Mancini.
